DUMPING'r-PLATFORM.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed December 2, 1913. Serial No. 804,272.

To all whom it may concern:

Be it known that I, JOHN HUNT, a citizen of the United States, residing at Dumont, in the county of Clear Creek and State of Colorado, have invented new and useful Improvements in Dumping-Platforms, of which the following is a specification.

This invention relates to dumping platforms adapted to be easily and quickly used for tilting wagons in order that the contents of the beds thereof may readily gravitate from the same.

An object of the invention is to provide a dumping platform of substantial structure upon which a wagon may be moved and secured.

The platform is tiltably mounted and means is provided for regulating the extent of tilting movement of the platform and means is provided for temporarily securing the platform in a tilted position. The frame upon which the platform is mounted is provided with movable supports adapted to be projected under one end of the platform when the same is in a horizontal position upon the frame for the purpose of holding the platform while the wagon is being moved from the same. Beyond the end of the platform there is located a chute into which the contents of the wagon bed are deposited.

In the accompanying drawings :-Figure 1 is aside elevation of the platform. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal sectional view of the platform.

Fig. 4 is a transverse sectional view of the same. Fig. 5 is a detailed sectional view of a portion of the platform. Fig. 6 is a perspective view of a lever which is used upon the platform.

The structure comprises a frame 1 provided at its upper portion with bearings 2. A shaft 3 is journaled in the bearings 2 and a platform 4 is fixed to the said shaft. The bearings 2 are open at their upper sides and consequently the shaft 3 may be lifted out of the bearings when desired. The platform 4 is provided at its side edges with shoulders 5 which are adapted to encounter shoulders 6 provided upon the frame 1 and thus the tilting movement of the platform 4 is limited. A cross piece 7 is mounted upon the frame 1 below one end of the platform 4 and detachable strips 8 are mounted upon the said cross piece. The said cross piece 7 and the strips 8 are adapted to limit the extent of swinging movement of the platform. A rack bar 9 is connected at one end with the end portion of the platform 4 and passes through a guide 10 provided upon the frame 1. A pawl 11 is pivotally mounted upon the frame 1 and is adapted to engage the rack bar 9 whereby the platform 4 may be held in tilted position. The platform 4 is provided upon its upper side with guide rails12 which extend longitudinally thereof and which are positioned in the vicinity of the side edges thereof. A cross piece 13 is adjustably mounted upon the platform 4 and its end portions are adapted to extend transversely across the guide rails 12. Studs 14 are mounted upon the frame 1 at the end of the platform 4 and strips 15 are provided at their ends with recesses 16 which are adapted to receive the studs. The strips 15 are piled one upon the other and the lowermost strip rests upon a cross piece of the frame 1. When the wagon is tilted the bed thereof is adapted to come in contact with the uppermost strip 15 and there fore the weight of the wagon bed at the end portion thereof is borne by the strips 15 and the. frame during the dumping operation. A chute 17 is mounted upon the frame 1 adjacent the end of the platform 4 and a detachable beam 18 rests upon the frame 1 and extends transversely across the upper portion of the chute 17 A door 19 is hingedly mounted upon the frame 1 and is adapted to be closed down over the chute 17 and when in a closed position the beam 18 serves as a support for the intermediate portion thereof. Shafts 20 are screw threaded in the side portions of the frame 1 and lugs 21 are pivoted to the inner ends of the said shafts. The shafts 20 are provided at their outer ends with handles 22 which are housed in boxes 23 provided at the sides of the frame 1.

When the platform 4 is in a horizontal position the shafts 20 may be turned so that the lugs 21 are projected under the end of the platform. A wagon is then drawn up over the door 19 and along the platform 4. The guide rails 12 will properly direct the wheels of the wagon along the said platform and when the front wheels come in contact with the cross piece 13 the wagon comes to a state of rest on the platform. The draft animals are then detached and the wheels of the wagon are made secure to the platform by lashing or by applying cross pieces or timbers in any suitable manner. The door 19 is then swung to an open position and the beam 18 is removed from over the chute 17. The shafts 20 are thenturned so that the lugs 21 are withdrawn from under the end of the platform 4:. Then by using a pry or jack under that end of the platform 4 which is remote from the chute 17 the platform ,4: and the shaft 3 are turned or tilted, this tilting movement continues until the platform 4: strikes one of the strips 8 and the bed of the wagon strikes one of the strips le. Thus the contents of the wagon bed will gravitate from the same into the chute 17. After the platform 4 has been tilted as above indicated the pawl 11 may be engaged with the rack 9 whereby the parts will beheldin tilted position After a wagon has been emptied of its contents the parts of the structure may be moved back to initial positions by reversing the operation above described.

The specific means for tilting the platform 4 comprisesa block 24 which is positioned upon the platform in vthe vicinity of one endL thereof and to which is fulcrumeda lever 25 by means of a detachable pin 26. A post 27 passes through the platform 4 and bears at its lower end upon the upper portion of the frame 1. This post is provided with alongitudinally disposed slot 28 through which the pin 26 passes. The post 27 is provided at its opposite side edges with teeth 29 and the lever 25 is provided with pivoted bails 30 which are connected together by means of springs 31 and which are held by the said springs in i engagementwith the teeth 29 upon the post.

Therefore it will be seen that by swinging the lever 25 one of the bails 30 is moved to a higher elevation than the other and the lowermost bail will remain in contact or engagement with one of the teeth 29 while the other bail will be moved to an uppermosttooth at the opposite side of the post. By swinging the lever in an opposite direction the positions of the bails 30 are reversed and consequently a lifting action is imparted to the end portion of the platform 4:. A chock block 32 is detachably mounted upon the end portion of the platform 4 and is adapted to be positioned behind the rear wheels of the wagon after the same has been drawn upon the platform and the said block is designed to h ld the Wagon against movement longitudinally of the platform during the initial tilting movement of the platform. The lever 25 is reversible with relation to the post 27 and the power end thereof may be disposed at either of the dentate sides of the said posts.

Having described the invention what is claimed is 1. A dumping structure comprising a frame, a platform tiltably mounted thereon, cross strips removably mounted upon the frame in the path of the platform, a chute carried by the frame, a door hinged at the upper edge of the chute and detachable cross strips mounted upon the frame between the said door and the platform.

2. A dumping structure comprising a frame, a platform pivotally mounted thereon, a post passing through the platform and engaging the frame and teeth at its opposite sides and provided with a longitudinal slot, a bracket mounted upon the platform and receiving the post, a lever fulcrumcd to the bracket, bails pivoted to the lever and engageable with the teeth of the post and springs connecting the bails together and holding them in engagement with the teeth of the post.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN HUNT.
